SNAP-SWITCH MECHANISM.

Application filed August 26, 1921. Serial No. 495,870.

To all whom it may concern Be it known that I, IRA R. SnL'rznR, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a new and use ful Improvement in Snap-Switch Mechanisms; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this appli-v cation, and represent, in-- Fig. 1 a view in side elevation of one form which my improved snap-switch mechanism may assume.

, Fig. 2 a plan view showing the same mechanism as installed in a. portion of a tubular housing. h

Fig. 3 a view thereof in side elevation.

Fig. 4 a view thereof in longitudinal section on the line 4-4 of Figure 3, showing the under side of the mechanism.

Fig. 5 a View thereof in longitudinal section on the line 5-5 of Figure 2, with the switch-mechanism in its open position.

Fi 6 a corresponding view with the switc -rnechanis1n in its closed position.

Fig. 7 a view in transverse section on the 'line 77 of Figure 6.

Fig. 8 a detached view in elevation of the trigger-like operating-member of the switch.

Iy invention relates to an improved switch-mechanism of the so-called' snapswitch type, such as are extensivelfr used for controlling electric-light circuitst small power-circuits such as vacuum-cleaner circuits, vibrator circuits, etc., the object being to simplify and improve the convenience of such switches, as well as to more readily in- ,dicate whether they are in their open or closed positions, or off or on.

With these ends in view, my invention con sists in certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claim.

In carrying out my invention, as herein shown, I employ a. trigger-like, rocking opcrating-member 11 having its upper edge 12 serrated and located in a longitudinally-arranged slot 13 in an oblong, insulating switch-base 14, the upper face 15 of which.

into it through the base 14- which is seen to be formed with a transverse passage intersecting its outer and inner faces and con sisting of the slot 13 and the chamber 18. The ends of the shaft. 16 are held in the bearing-grooves 17 by the body-part of the frame 19, as clearly shown in Fig. 5. The

lower end of the said operatin -member 11 Z3 is formed with a slot 22 adapting it to he engdgcd with the slotted upper end of a sheet-metal switch-rocker or actuator 23 having a perforation 24, receiving a small tonghe 25 formed upon the inwardly-turned arm 26 of the switch-frame 19, the rocker or aqttuator23 rocking back and forth upon he said tongue 25, as upon a pivot. The lower end of the part 23 is bent to form a hook- 27 coacting with a switch 28 to throw the same into its open, or off, position, as shown in Figure 5, and-into its closed, or on, position, as shown in Figure 6, the switch having a shanx 29 sliding hack and forth through a bearing-opening 30 in the arm 31 of the frame 19, and encircled by a spring 32, which throws the switch in one direction or the other, as it passes ts deadcenter with relation to the tongue 25 of the part 23. As the switch is thrown; into its. 7

closed position, its contact-arms 83" Figure 4) engage with contact-plates 3% and 35 in serted into the lower face of the insulating base 14 and connected with terminals 36 and 37 carrying binding-screws 38 for the at" tachment of the conductors 39.

As shown, the switch-mechanism described is fastened by screws 40 to, and depends from, the central portion of a transverselyb0wed mountingplate il secured by screws 42 passing through its ends to the tubular handle 43 of a vacuum-cleaner the said handle being formed in its upper face with a longitudinal installationslot 4:4 covered by' the plate 41 and. provided to permit the entrance of the switch-mechanism into the handle, and the said platebeing formed with a slot 45 tor the upward projection through it of the outer end of the trigger-like operating-memher 11. t

I claim: 3

The combination with the tubular handle of a vacuum-cleaner, the said handle being formed on its upper face with a lon 'tudinal installation-slot, of a transversely owed, slotted mounting-plate superimposed upon the said handle to cover the said installation-slot and extended beyond the ends thereof for being attached to the upper face of the said tubular handle, an oblong insulatingsWitch-base having its upper face roundplate to which ed to fit the'conoave inner face of the sai it is fastened and having its inner face formed with a recess or chamber Witnesses:
